Cook bacon in 12-inch non-stick skillet over medium-high heat until crisp, about 3 minutes. Use slotted spoon to set bacon aside. Drain off all but 2 Tbsp fat.
Add garlic and leeks to skillet. Cook until fragrant, about 2 minutes. Add cabbage, chicken stock, white wine and beans. Gently toss to combine. Simmer until cabbage is just beginning to wilt, about 3 minutes. Crumble bacon. Toss cooked mixture with bacon, sage, chives and pepper. Adjust seasoning. Serve immediately.
